Description

Technical Field

[0001] This utility model relates to the field of SPC flooring coating technology, and in particular to a coating device for an SPC flooring production line. Background Technology

[0002] With the rapid development of modern building decoration materials, SPC composite flooring has been widely welcomed in the market due to its environmental protection, wear resistance, and ease of installation. In the production process of SPC flooring, the lamination process is a crucial step, as it directly affects the surface quality, wear resistance, and aesthetics of the flooring.

[0003] However, the existing SPC flooring production line laminating device is inconvenient to fix the position of the conveyed base plate during use, and the heating is not uniform enough during use, which can easily lead to unstable lamination. Therefore, there is a need for an SPC flooring production line laminating device. Utility Model Content

[0004] The purpose of this invention is to provide a laminating device for an SPC flooring production line, which solves the problems of inconvenience in fixing the position of the conveyed base plate and uneven heating during use, which can easily lead to unstable laminating.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a film coating device for an SPC flooring production line, comprising a base and a film coating mechanism installed on the right side of the base, wherein the film coating mechanism comprises a conveying component and a film coating component; The conveying assembly includes a first motor, a synchronous pulley, a synchronous belt, a bidirectional screw, a mounting base, a clamping plate, rollers, a long support rod, a top roller, and a short support rod. The first motor is mounted at the front of the base, and the output end of the first motor is mounted on the synchronous pulley. A bidirectional screw is fixedly mounted behind each of the synchronous pulleys. The synchronous pulleys are driven by the synchronous belt. The mounting base is meshed with both ends of the bidirectional screw. The top of the mounting base is fixed to the clamping plate. The rollers pass through the interior of the clamping plate and are arranged in an array inside the device. A long support rod is fixedly mounted on the top of the base, and a top roller is mounted on the top of the long support rod. A short support rod is mounted on the right side of the long support rod. The coating assembly includes a central support, a second motor, a pressing bottom roller, a pressing top roller, a lower gear, an upper gear, a heating groove, and a right-side conveyor seat. The central support is fixedly installed on the right side of the base, and the second motor is fixedly installed behind the central support. The pressing bottom roller is installed at the output end of the second motor. The pressing top roller is symmetrically installed on the top of the pressing bottom roller. The lower gear is fixedly installed in front of the pressing bottom roller, and the upper gear is fixedly installed in front of the pressing top roller. The heating groove is arranged in an array inside the pressing bottom roller, and the right-side conveyor seat is fixedly installed on the right side of the central support.

[0006] Preferably, the bidirectional screw array is equipped with four sets. The first and fourth sets of bidirectional screws are provided with a set of synchronous pulleys in front of them, and the second and third sets of bidirectional screws are provided with two sets of synchronous pulleys in front of them. The bidirectional screws are all driven by the cooperation of the synchronous pulleys and the synchronous belt.

[0007] Preferably, two sets of clamping plates are symmetrically arranged outside the bidirectional screw, and the two sets of clamping plates form a translation structure through the cooperation of the mounting base and the bidirectional screw.

[0008] Preferably, the clamping plate is slidably mounted on the outside of the roller, and the bottom cross-section of the clamping plate is triangular.

[0009] Preferably, the pressing bottom roller and the pressing top roller form a rotating structure through the cooperation between the lower gear and the upper gear, and the upper gear and the lower gear mesh with each other.

[0010] Preferably, the heating grooves are arranged in an array on the inner side of the pressing top roller, and the heating grooves are close to the surface of the heating groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. During use, there are two sets of clamps outside the bidirectional screw. Therefore, when the bidirectional screw rotates, the clamps will move in opposite directions. By adjusting the distance between the two sets of clamps, the device can be adapted to clamps of different widths. The two sets of clamps are also symmetrical about the center line of the bidirectional screw. Therefore, after adjusting the distance between the clamps, the base plate to be transported will still be kept in the center position of the two sets of clamps, which is convenient for transporting SPC flooring.

[0012] 2. During use, the second motor drives the pressing bottom roller to rotate, which in turn drives the front heating tank to rotate. When the heating tank rotates, it drives the upper gear meshing at the top to rotate, which in turn drives the pressing top roller to rotate. The upper gear meshes with the lower gear, so the pressing bottom roller and the pressing top roller rotate in opposite directions. This facilitates pressing the base plate and film together between the pressing top roller and the pressing bottom roller, which are internally transmitted to the pressing top roller and the pressing bottom roller. The pressure fixes the film and the floor together. At the same time, multiple sets of pressing bottom rollers and pressing top rollers can press and heat the floor and film multiple times, making the film coating more stable and firm.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 like Figure 1-6As shown in the figure, an SPC flooring production line laminating device includes a base 1 and a laminating mechanism installed on the right side of the base 1. The laminating mechanism includes a conveying component and a laminating component. The conveying assembly includes a first motor 2, a synchronous pulley 3, a synchronous belt 4, a bidirectional screw 5, a mounting base 6, a clamping plate 7, rollers 8, a long support rod 9, a top roller 10, and a short support rod 11. The first motor 2 is installed in front of the base 1, and the synchronous pulley 3 is installed at the output end of the first motor 2. The bidirectional screw 5 is fixedly installed behind the synchronous pulley 3. The synchronous pulleys 3 are driven by the synchronous belt 4. The mounting base 6 is meshed at both ends of the bidirectional screw 5. The top of the mounting base 6 is fixed to the clamping plate 7. The rollers 8 pass through the interior of the clamping plate 7 and are arranged in an array inside the device. The long support rod 9 is fixedly installed on the top of the base 1. The top roller 10 is installed on the top of the long support rod 9, and the short support rod 11 is installed on the right side of the long support rod 9. The coating assembly includes a central support 12, a second motor 13, a pressing bottom roller 14, a pressing top roller 15, a lower gear 16, an upper gear 17, a heating groove 18, and a right conveyor seat 19. The central support 12 is fixedly installed on the right side of the base 1. The second motor 13 is fixedly installed behind the central support 12. The pressing bottom roller 14 is installed at the output end of the second motor 13. The pressing top roller 15 is symmetrically installed on the top of the pressing bottom roller 14. The lower gear 16 is fixedly installed in front of the pressing bottom roller 14. The upper gear 17 is fixedly installed in front of the pressing top roller 15. The heating groove 18 is arranged in an array inside the pressing bottom roller 14. The right conveyor seat 19 is fixedly installed on the right side of the central support 12.

[0017] The bidirectional screw array consists of four sets. The first and fourth sets of bidirectional screws 5 have a set of synchronous pulleys 3 in front of them, while the second and third sets of bidirectional screws 5 have two sets of synchronous pulleys 3 in front of them. The bidirectional screws 5 are all driven by the cooperation of the synchronous pulleys 3 and the synchronous belt 4. During use, the first motor 2 drives the synchronous pulleys 3 to rotate, and then the synchronous pulleys 3 drive the different synchronous pulleys 3 on the right side to rotate through the connected synchronous belt 4, thereby driving the different bidirectional screws 5 behind to rotate. At the same time, the four sets of bidirectional screws 5 with synchronous belts are set inside the device so that the bidirectional screws 5 will not produce too much error when driving the top clamping plate 7 to move back and forth, ensuring that different parts of the clamping plate 7 are relatively stable and uniform when moving horizontally.

[0018] Two sets of clamping plates 7 are symmetrically arranged outside the bidirectional screw 5. The two sets of clamping plates 7 form a translation structure through the cooperation of the mounting base 6 and the bidirectional screw 5. During use, since there are two sets of clamping plates 7 outside the bidirectional screw 5, the bidirectional screw 5 will cause the clamping plates 7 to move in relative directions when it rotates. By adjusting the distance between the two sets of clamping plates 7, the device can be adapted to clamping plates 7 of different widths. Furthermore, the two sets of clamping plates 7 are symmetrical about the center line of the bidirectional screw 5. Therefore, after adjusting the distance between the clamping plates 7, the base plate to be transported will still remain in the center position of the two sets of clamping plates 7, which facilitates the transport of SPC flooring.

[0019] The clamping plate 7 is slidably installed on the outside of the roller 8. The bottom cross-section of the clamping plate 7 is triangular. During the translation process driven by the bidirectional screw 5, the clamping plate 7 will translate outside the roller 8. The bottom of the clamping plate 7 is triangular, which can avoid the problem of the clamping plate 7 not being able to move due to friction between the clamping plate 7 and the roller 8 during the translation process.

[0020] Example 2 like Figure 5 and Figure 6 As shown, this embodiment further explains Example 1. The pressing bottom roller 14 and the pressing top roller 15 form a rotating structure through the cooperation between the lower gear 16 and the upper gear 17. The upper gear 17 and the lower gear 16 mesh with each other. During use, the second motor 13 drives the pressing bottom roller 14 to rotate, and then the pressing bottom roller 14 drives the front heating groove 18 to rotate. When the heating groove 18 rotates, it drives the upper gear 17 meshing at the top to rotate, thereby driving the pressing top roller 15 to rotate. The upper gear 17 and the lower gear 16 mesh with each other, so the pressing bottom roller 14 and the pressing top roller 15 will rotate in opposite directions, which facilitates pressing the bottom plate and the film between the pressing top roller 15 and the pressing bottom roller 14, which are internally transmitted to the device, together. The film and the floor are fixed together by pressure. At the same time, multiple sets of pressing bottom rollers 14 and pressing top rollers 15 can press and heat the floor and the film multiple times, making the film coating more stable and firm.

[0021] Heating grooves 18 are arrayed on the inner side of the pressing roller 15. The heating grooves 18 are close to the surface of the pressing roller 15. During use, the heating grooves 18 can heat the pressing roller 15 from inside the pressing roller 15. By heating the floor, the film can adhere to the floor more stably. At the same time, multiple sets of heating grooves 18 are set inside the device to make the film coating more uniform and avoid wrinkles and bubbles in the film coating.

[0022] Working Principle: First, the film to be coated is placed above the long support rod 9. Then, guided by the short support rod 11, the film is guided to the position between the pressing bottom roller 14 and the pressing top roller 15. The base plate to be coated is then conveyed upwards to the center support 12 via rollers 8. During this conveying process, the first motor 2 drives the synchronous pulley 3 to rotate. The synchronous pulley 3, through the connected synchronous belt 4, drives different synchronous pulleys 3 on the right side to rotate, thereby driving different bidirectional screws 5 to rotate. Simultaneously, four sets of bidirectional screws 5 are installed inside the device with synchronous belts, ensuring minimal error when the bidirectional screws 5 move the top clamping plate 7 back and forth. This ensures stability and uniformity of different parts of the clamping plate 7 during translation. Two sets of clamping plates 7 are located outside the bidirectional screws 5. Therefore, the rotation of the bidirectional screws 5 causes the clamping plates 7 to move in opposite directions. Adjusting the distance between the two sets of clamping plates 7 allows the device to adapt to different orientations. The clamping plates 7 are of different widths, and the two sets of clamping plates 7 are symmetrical about the center line of the bidirectional screw 5. Therefore, after adjusting the distance between the clamping plates 7, the base plate to be conveyed is still kept in the center position of the two sets of clamping plates 7, which facilitates the conveying of SPC flooring. Then, the second motor 13 drives the pressing bottom roller 14 to rotate, and then the pressing bottom roller 14 drives the front heating groove 18 to rotate. When the heating groove 18 rotates, it drives the upper gear 17 meshing at the top to rotate, thereby driving the pressing top roller 15 to rotate. The upper gear 17 and the lower gear 16 mesh with each other, so the pressing bottom roller 14 and the pressing top roller 15 will rotate in opposite directions, which facilitates pressing the base plate and film together between the pressing top roller 15 and the pressing bottom roller 14, which are internally transmitted to the device. The film and flooring are fixed together by pressure. At the same time, multiple sets of pressing bottom rollers 14 and pressing top rollers 15 can press and heat the flooring and film multiple times, making the film coating more stable and strong.

[0023] Additional notes: The elastic stretching issue of timing belts can be resolved in the following ways: 1. Compensation design for elastic expansion and contraction, including pre-stretching treatment and material selection. Pre-stretching treatment: The timing belt is pre-stretched before installation (e.g., operating under rated tension for 24 hours) to eliminate initial inelastic elongation. Engineering practice shows that pre-stretching can reduce initial elongation by more than 80%. Material selection: Polyurethane (PU) timing belts: High elastic modulus, lower elongation rate than rubber belts. Carbon fiber reinforced timing belts: Increased tensile stiffness, reducing dynamic elongation.

[0024] 2. Suppression of dynamic synchronization error, including short center distance design: shorten the center distance of the timing belt pulleys (e.g., ≤ 5 times the diameter of the smaller pulley), reduce the length of the timing belt suspension section, and reduce the accumulation of elastic deformation.

[0025] In summary, elasticity and stretching are not uncontrollable factors, but rather need to be quantified in the design (e.g., allowable stretching rate ≤ 0.3%). In practical engineering, synchronous belt drives can achieve an accuracy within ±0.5° (DIN 7721 standard), which can meet the needs of most industrial scenarios.
